Hiram, I like Tesoro detectors a lot.
They do what they are supposed to do.
Lightweight, trim and compact, easy to use, and lifetime warranty.
Since you are new to this, AND undecided, I would advise you purchase a Tesoro Compadre.
They are getting excellent reviews because people are beginning to notice how well they work.
About $150 brand spanking new, and you'll have a friend for life that only eats batteries once and a while!
I'd almost guarantee if you ever upgrade to a fancier machine, you would keep it for a loaner, or spare.
Good luck, there's a lot of treasure out there...
